“Cryogenics – An Overview and Cryo at JLab”
David Kashy
Jefferson Lab
Abstract:
This talk will give a brief introduction to the science/engineering of cryogenics.
The applications of cryogenics and cryogenic fluids are many, this talk will focus
mostly on cryogenic systems and applications at Jefferson Lab. Some of the critical
design/engineering considerations will be reviewed. Several components of JLab's
cryogenic systems will be highlighted including cryogenic targets, cryogenic
distribution, and a high level overview of the many portions of the laboratories
many cryogenic systems. Gas and liquid storage systems will be discussed as well as
the refrigerators/liquefies that convert the gas to liquid. Key operational processes
including helium purification will be discussed as well as process control that allows
the systems to run 24/7 without continuous staffing. At the end the attendee should
have a better feel for the scope of the JLab cryogenics system and cost and effort to
operate the systems here at JLab.
